Finding gamers is easy enough. If you set bait in some way, they will come.
The challenge is more oriented towards finding people that want to play the game you want to play, the way you want to play it, on the days your available to play it, as often as you want to play, ad nauseum. So finding the "right" group is far more difficult depending on what you want. It's really easy to find some players if you say you're going to run some well known adventure. Most people in my area are not big on the role-playing part of the game, from what I've seen.
